New research has shown how the quantum mechanical principle of strong coupling opens unrivalled possibilities for designing optical filters. A team of researchers from the University of Cologne, ...

A dust sensor is an optical electronic system to detect fine particles such as dust. In principle, an optical dust sensor detects the dust particle concentration the in air by using an optical sensing ...

It’s always interesting to see how scientists and engineers have exploited—in the positive sense of the word—somewhat obscure, fundamental physics principles to create innovative sensors. For example, ...

Imaging technology has transformed how we observe the universe—from mapping distant galaxies with radio telescope arrays to unlocking microscopic details inside living cells. Yet despite decades of ...
